Hi all!
A few days ago I upgraded my DMA to 10.4.0.0-15151-CU9 and Yesterday this alarm raised: 'Cassandra cluster health is red. Cassandra cluster is no longer available. 0 out of 0 Cassandra nodes are unavailable: .'
It's a single DMA with two HDD, one for the DataMiner installation and the second dedicated to Cassandra.
I'm scratching my head trying to figure out where the problem lies.... any suggestion?

Hi Riccardo
You can check the status of the connection with the DB on this 2 log files SLCassandrahealth and SLDBConnection within C:Skyline Dataminerlogging folder. Check first the cassandra health file and if you see everything correct you can clear the alarm if not check the second file mentioned to have an idea on what's going on.
